Is it possible to export a hidden Silverlight Chart to Image?

I tried to export a Visifire Radar chart to Image using FJ.Core.dll in Silverlight 5. It is working fine if the chart is placed as a visible element in the UI.
Unfortunately I don't want to show the chart in the exporting window as the window size is very small. So I cant put the chart control as a visible UI element on that window. Is there a way to export the chart image with out showing it on the UI?. The version of Visifire chart is 4.1.5.0 and FJ.Core version is 1.0.0.0

In Visifire chart updates whenever a property value changes or a DataSeries collection is changed. If you want an event at initial-render then Rendered event should work for you. Are you changing any property at real-time and trying to do some operation when chart updates?

But i have one more question! If I try to capture image from chart, which in current moment in animation state, i got image on which animation not finished. how can i get image of finished chart? Also i cant disable animation before creating chart. I can disable it only after request of creating chart image.
